Federal regulators have closed an investigation into what went wrong when a SpaceX Starship spacecraft — part of the most powerful launch system ever constructed — exploded during a January test flight.

When SpaceX's Starship takes off next time from South Texas, it will have a few touch-ups from the last time the rocket launched in January and rained flaming debris down near the Turks and Caicos Islands.

SpaceX is targeting a late Wednesday night launch of a Falcon 9 rocket carrying Starlink internet satellites to low Earth orbit.
